Don't know how to deal with this (May Trigger)

My brothers were abusive (1 physically the other sexual harrassment and once physical) to me up until my early 20's...I never considered myself abused though but had alot of mental problems...Not liking to be touched etc...Anyways I went into therapy several years ago and my therapist at that time said it was just sibling rivalry...That my brother was a child himself...

I was kicked down the basement stairs (once I know for a fact) was thrown against the refridge and dislocated my shoulder...Was beatin on repeatedly until I had huge lumps and bruises on my arms was choked until I almost passed out and on and on...

The brother that did the physical abuse and I developed a good relationship after he moved away from home...This past June he got married (4th time) and he made a comment at the reception and it threw me into a tizzy...I went in the ladies room and slid down the wall b/c I realized that sucker that hurt me all those years was still in him...

The brother that sexually harrassed me was charged with felony stalking of another church member and he's out of my life...

I am in therapy with a new therapist who is great and yesterday we had a session, I was an emotional mess during the session and than it was like in a blink of an eye I was fine...I've been fine all day today, no crying, no raging, nothing...

I got an invitation from my brother for a New Years Eve Party and I don't want any part of him...

Is my old T right that it was just sibling rivalry and I'm dwelling on the past and I should go to the party?...HELPPPPPPPPP

First off, if you don't want to go, don't go. No matter what your therapist says, or your brother thinks. If this guy abused you, and is still joking about it, not much has changed, and you don't need to subject yourself to something that might be harmful. Just tell him honestly that it doesn't work for you. Not to mention that it might trigger post traumatic stress disorder.....It sounds like you've been working on getting your life together, and you don't have to throw it up in the air just because he askes. Keep with the therapy, and good luck!
